<span>The correct answer is D) fusion. In fact, nuclear fusion occurs when two (or more) small nuclei combine to form a heavier nucleus. In the process, a large amount of energy is released, according to Einstein's formula </span>

<span>, where m is the mass converted into energy in the reaction. An example of nuclear fusion is the fusion of two nuclei of hydrogen into a nucleus of helium-4.</span>
The speed after 10 s is 20 m/s
<h3>What is the speed after 10 s?</h3>
Given that we have the following;
force = 2800 N
Mass = 1400 kg
time = 10 s
Recall that;
F = ma
F = force
m = mass
a = acceleration
a = F/m
a = 2800 N/1400 kg
a = 2 m/s^2
Now;
v = u + at
v = ??
u = 0 m/s
a= 2 m/s^2
t = 10 s
v = at
v = 2 * 10
v = 20 m/s

Answer:
V = 25.3 , θf = 36.7° below the horizontal
Explanation:
Given Vo = 22m/s , θ = 23°
Vx = VoCosθ
Vy = VoSinθ – gt
t = total time of flight
Hi there!
On a level road:
∑F = Ff (Force due to friction)
The net force is the centripetal force, so:
mv²/r = Ff
Rewrite the force due to friction:
mv²/r = μmg
Cancel out the mass:
v²/r = μg
Solve for v:
v = √rμg
v = √(25)(9.81)(0.8) = 14.01 m/s
1.97 E-7 m should be right. I took this a while ago.
